Many Romantic-Era composers used Classical-Era forms in one way or another. The expressive impact of Romantic-Era music was not antiquated or diluted by the use of Classical-Era forms. Tchaikovsky’s adoption of Classical-Era sonata form for his Overture-Fantasy, Romeo and Juliet, in no way inhibits its powerfully Romantic expressivity. In this work, Tchaikovsky created a piece of music that can be appreciated both as abstract music and as program music.
